Board Optimization - [DBTech] vB Optimise 2.0.1 (Lite)

vB Optimise Lite

This is ported from my original version released for vBulletin 3.8 located here. In this release I have re-coded vB Optimise from the gound and focused stability over features.

Professional version & feature list available @ www.DragonByte-Tech.com/forum
Priority support for Lite version is handled at the Developers Website.


What does it do?

vB Optimise is intended to optimise vBulletin software by integrating several PHP "cachers" and handling data before vBulletin. This works by encountering and handling data prior to vBulletin in order to skip the arbitary execution that would be more server intensive.

Real-Life Statistics

We've teamed up with some Big Forums to show you the impact of vB Optimise, you can view this public chart which shows both our statistics and theirs:

Features - Lite

• Supported Extensions
  • APC
  • eAccelerator
  • Memcache
  • XCache
  • WinCache
  • Filecache
• Style Cacher
  Caches style data to globally reduce a query within all vBulletin forum-based pages.
• Template Cacher
  Caches template data to globally reduce a query within all vBulletin forum-based pages.
• Datastore Cacher
  Forces custom datastore items from modifications (including those from vB's blogs) to use your configured Datastore Cache method instead of being forced into the database. This reduces page queries by where affected.
• vB CMS Template Caching
  (Automatic) Corrects many uncached templates within vB CMS to reduce upto 20+ queries on CMS pages (number varies based on content).
• Optimal Settings Check
  Provides a quick interface to identify possible settings which can be changed on your forum for further optimisation.
• Self-System Tester
  Provides a relatively straight-forward system check to ensure your vB Optimise installation works fully.
• Automatic Cache Flusher
  Automatically flushes cache within the Admin CP based on specific triggers to make sure content does not remain stale on your forum.
• XCache Authentification
  Supports XCache Admin Authentification by allowing you specify the username/password in a configuration if needs be.

Features - Pro

• Notices Cacher
  Caches users dismissed notices to reduce a near-global query within all vBulletin forum-based pages.
• Showgroups Cacher
  Caches the showgroups query which becomes more intensive as your user-base grows.
• Forum Display Query Enhancement
  Enhances a stock vBulletin query within Forum Display to speed up the page.
• Forum Home WOL Cache
  Caches Forum Home "Who's Online" to remove an intensive query and allow larger sites to display this data without impact.
• vB Cache Override (Feature not available on vBulletin 3)
  Ability to override vBulletins new built-in database cacher for the CMS / Forum Sidebar Blocks to remove anything from 1 to 20+ queries based on your content.
• Full Guest Caching
  Ability to cache entire pages and serve them saving not only hundreds of queries but upto 90% of CPU processing towards Guests.
• Statistical Resource Savings
  Ability to see just exactly how many queries per day vB Optimise has saved your database. You'll be surprised at the numbers.
• Forum Resource Statistic
  Shows off vB Optimise resource saving statistics directly within forumhome statistics.
• ....and more!

Release Notes

If you've used vB Optimise before you'll be aware the previous version had phrase caching, however this caused complications with the way phrases are used within vBulletin so it has not been ported over at this time.

FAQ

Q: I have WinCache installed, but vB Optimise tells me it's not?
A: WinCache only introduced OpCode support in version 1.1, if you're using version 1.0.x you will need to upgrade.

Q: I'm using the XCache method, flushing doesn't work?
A: If you have XCache authentification, turn the admin option on within vB Optimise Settings, then edit ./vboptimise/config.php and specify your XCache username/password. Alternatively you can disable XCache authentification within php.ini:

xcache.admin.enable_auth = Off

Q: I have eAccelerator installed, but vB Optimise tells me it's not?
A: eAccelerator does not provide the caching extension by default, you will need to recompile PHP with additional flags. For more information read eAccelerator documentation located here: http://eaccelerator.net/wiki/CompileConfiguration (Specifically look at: with-eaccelerator-shared-memory)

No problem Good luck with your optimisations!

Whats this mean mate :/ i get this with memcache

To those receiveing the Opcache Operator error with xCache:

Your Opcache Operator extension is functioning, however it is unable to store data. Please check your extension configuration.

This might happen if you are using SuPHP as your PHP handler instead of DSO (mod_php) or FastCGI.

If you don't know what your PHP handler is but you have ssh access, you can run this command if you have cPanel (or just ask your host):

/usr/local/cpanel/bin/rebuild_phpconf --current

And this will be the output (if you're SuPHP is your handler):

Available handlers: suphp dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: suphp (or cgi)
PHP5 SAPI: suphp
SUEXEC: enabled

If DSO is your PHP handler, you'll see something like:

Available handlers: suphp dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: cgi
PHP5 SAPI: dso
SUEXEC: enabled

Why does SuPHP produce this error?

PHP optcode caching doesn't work 100% with SuPHP because SuPHP doesn't use a shared user when processing PHP files.

I'd definitely talk to your webhost before making any changes or get an individual opinion on your particular configuration. FastCGI on the limited resources (like limited cloud hosting) many forum owners are hosted on will usually outperform even DSO with an accelerator.

Deceptor Helped me fix my problems top mod top guy and top support <3

Animemike was missing the libevent 1.4 library for Memcached, I helped him reinstall it and initialise the memcached instance - everythings working good now

Yeah, there are other commands to check your PHP handler like speccing the php.ini, but I'm unfamiliar with them.

My post is mainly aimed at anybody frustrated with Xcache in particular, as it will cache but it wont allow cache fetching. They'd be looking for a long time if they weren't aware of suPHP's lack of optcode support.

I am also getting the errors. This is what I get:

Available handlers: dso cgi none
DEFAULT PHP: 5
PHP4 SAPI: none
PHP5 SAPI: none
SUEXEC: enabled

Can you guys see anything wrong here? and if so what do you guys recommend?



Edit never mind. Deceptor helped me get memcached installed. He is a great guy!

[MikeWarner]

Since installing this, I'm asked to give my xcache login details when editing a users usergroup. How can I stop this from happening?

[Deceptor]

MikeWarner - You either need to disable XCache authentification in php.ini, or enable XCache Authentification within the vB Optimise options and edit /vboptimise/config.php and enter your XCache username/password (in plain text) so vBO can automatically log in for you.
